GOTHENBURG - January 22, 2011: The technology and the solutions that the Lindell family use to live the
"One Tonne Life" are already available or will become available in the very
near future.

A-hus President Peter Mossbrant explains: "Our goal is to make
low-energy wooden houses available to a broad market. More people should be
able to live climate-smart - without compromising on comfort, function or
design. We offer everything under one wellinsulated roof. In fact, we will
start selling this type of house in the end of January 2011." The plans for
the villa were drawn up by architect Gert Wingårdh. He has made the white
house more energy - efficient and given it a more interesting appearance
with the characteristic protruding framework around each window, the
wind-catcher in the entrance hall and the large integrated veranda
alongside the living room. Together with the black roof and the
south-facing solar panels, the house has a truly unique personality all on
its own.

Sealed climate shell, solar cells and solar panels
The "One Tonne Life" house has triple-layer walls with exceptional
insulation capability and minimal air leakage. Other important features are
improved insulation in the roof and foundations, as well as lowenergy
windows and doors.

The wind-catcher in the entry hall prevents large airflows between the
inside and the outside. This creates a comfortable climate inside the house
and the energy consumption becomes lower. The protruding frames around the
windows shade the interior when the sun is high in the summer sky, yet let
in the winter sun's energy when it is low on the horizon.

In order to ensure a supply of fresh air to the well-encapsulated house,
there is a ventilation unit that sucks out spent poor-quality air and
replaces it with fresh, tempered air delivered to the bedrooms, living room
and other public areas. The heat in the spent air is recycled.

The building's heating requirements are largely met by the incoming air,
the occupants' body heat and heatgenerating household appliances.
Supplementary underfloor heating is installed on the bottom floor. The
solar cells on the roof and the south-facing facade generate electricity
that provides additional heating or is used to recharge the electric car.
Any electricity that is not consumed by the family is fed into the national
grid The solar panels on the carport roof meet a large portion of the
household's heating and hot water requirements during April to October.
When the sun is not shining and the accumulator tanks have no solar power
stored, the Lindell family get renewable energy from Vattenfall.

Volvo C30 Electric

Volvo C30 Electric - up to 150 km on one charge
The family's Volvo C30 Electric operates quietly and emits no carbon
dioxide at all when it is recharged with renewable electricity. The
electric car is part of Volvo Cars' drive to promote electrification. It
offers the very same comfort, interior space and safety as the standard
version of the C30. The difference is that the Volvo Electric C30 is
powered solely by electricity.

The "One Tonne Life" project gives Volvo Cars the opportunity to study
how the electric car fits in with a modern family's lifestyle.

"We will reap immense benefit from the project in our ongoing
development of electric cars. It will give us clear information about what
we need to deliver so buyers feel that a battery-powered car is attractive
and costeffective to drive and own," says Lennart Stegland, manager of
Volvo Cars' Special Vehicles division. The Volvo C30 Electric is powered by
lithium-ion batteries that are recharged via a regular wall socket. A full
charge takes about eight hours. The range on a full charge is up to150
kilometres. "150 kilometres is much more than the average European commuter
drives in one day. In "One Tonne Life" this range will cover most of the
Lindell family's transport requirements," says Lennart Stegland.

Smart energy solutions
Climate-smart and energy-producing houses are an important piece of the
puzzle in the development of intelligent electricity grids, which in turn
are an important ingredient in a sustainable society. Vattenfall has
several projects dealing with the development of intelligent electricity
grids and energy solutions "We will reap immense benefit from the project
in our ongoing development of electric cars. It will give us clear
information about what we need to deliver so buyers feel that a
battery-powered car is attractive and costeffective to drive and own," says
Lennart Stegland, manager of Volvo Cars' Special Vehicles division. The

Smart energy solutions
Climate-smart and energy-producing houses are an important piece of the
puzzle in the development of intelligent electricity grids, which in turn
are an important ingredient in a sustainable society. Vattenfall has
several projects dealing with the development of intelligent electricity
grids and energy solutions for households that focus on electricity
monitoring and energy efficiency enhancement. As a result, some homeowners
can be both electricity consumers and small-scale electricity producers,
for instance by utilising solar cell technology.

In "One Tonne Life" Vattenfall is making a variety of contributions
including Energy Watch - cuttingedge technology for measuring the family's
electricity consumption in real time. "We're helping the Lindell family
keep a watch on their electricity consumption and also helping the family
members use their electricity in an efficient way," says Torbjörn Wahlborg,
President of Vattenfall Norden. He adds: "We are also working on a further
development of the electricity grid so that a family whose home is fitted
with solar cells is able to sell its surplus to us when their own
production exceeds demand. At the same time, they get a secure supply of
electricity from green sources such as windpower or hydropower when the sun
is not shining."

Eco-conscious choices
Food represents about one-quarter of a household's climate footprint,
and supermarket chain ICA sees considerable potential here for reducing
carbon dioxide emissions through active choices. "We have a wide range of
eco-marked, ecologically produced and locally grown produce. By
participating in "One Tonne Life" we hope to find new ways of involving and
helping our customers make simple but significant choices both in the
supermarket and in the kitchen at home," says ICA environmental affairs
manager Maria Smith.

Energy-efficient household appliances
Household appliances account for up to half of a normal household's
total energy consumption - and the way these appliances are used also
affects the size of the electricity bill. Over the past 15 years, Siemens
has cut energy consumption of its appliances by up to 80 percent, and its
figures for energy and water consumption are of world class.

"Our aim is to help ensure that tomorrow's household can continue to
live as comfortably as today's, but with due care for the environment. The
products that the Lindell family use show how far we have already come. We
will also help them use their white goods in the best possible way," says
Martin Knobloch, President of Siemens Home Appliances Northern Europe.
